摘　　要：将可视性分析得到的视线和视域结果用于最优路径搜索过程中,并同时考虑到地形特征如土地覆盖或土地利用,高程及坡度等对通行能力的影响,得到了能避开监视的安全隐蔽路径,比较隐蔽的最不可视性路径和视野较开阔的最可视路径。该方法适用于军事,旅游,城市规划等领域,具有重要的军事意义与民用价值。Visibility information such as line-of-sight and viewshed got from terrain visibility analysis was applied to least-cost path planning, and the influence of terrain features such as land use/cover, elevation and slope on vehicles＇ travel ability was considered. The safety path which can avoid being watched, and the least visible path which is convert and the most visible path with open eyeshot could be got. This method is suitable for military, travel, city planning and has significant military meaning and civil merit.
